【The Waribashi Effect】3,000 times the sex drive! The story of turning the innocent sister of your dreams into a monkey with aphrodisiac.

Synopsis

I love my tutor’s sister Ruri.
I want her to be my wife in the future.
But I’m too old for them to take any notice of me at all.

So I thought, “Why not?
I had my sister attack me.

I’m not going to be able to do that.
For that reason I bought some questionable drugs on the internet.
If you take this, you’ll have an uncontrollable sex drive.
I’ve heard that it makes you want to have sex so badly.

When I took it, my sister attacked me just like she wanted.
The operation was a success!
You are now my wife!

But there was one thing that happened that I didn’t expect.
What a surprise, my sister’s sex drive has not subsided at all.

The kind sister felt sorry for her, but she couldn’t overcome her sexual desire.

It attacked me again and again.

She wouldn’t be satisfied with just one or two times, but every day until her penis was no longer erect.

I’m going to be squeezed.

I’ve definitely wanted to have sex with my sister.
But you’re still too much of a monkey.
